Answer this question truthfully
### Question: Why log in?
### Response: You don't have to log in to read any MediaWiki wiki. You don't even have to log in to edit a MediaWiki wiki - anyone can edit almost anypage, even without logging in.
However, it's still a good idea to log in, for these reasons:
Other users will be able to recognise you by your username when you make changes to pages. As a "name" an IP address is somewhat clumsy. Also, if you use computers at different locations (home, office, internet cafe, etc.) you have a different IP-address in each case; even in the same location, depending on the Internet connection, the IP-address may be different each time. Therefore a username is better to maintain an identity. You will have your own user page where you can write a bit about yourself, and a user talk page which you can use to communicate with other users. You will be able to mark an edit as minor, which avoids inconvenience for other users. You will be able to keep track of changes to pages you are interested in using a watch list. If you choose to give an email address, other users will be able to contact you by email. This feature is anonymous - the user who emails you will not know your email address. You don't have to give your email address if you don't want to. Check the privacy policy of the individual site you're visiting, if any (for example, Wikipedia's draft privacy policy) You will be able to rename pages. You will be able to set your own preferences, to change things such as: The number of pages displayed in Recent changes The fonts, colours and layout of the site, by using different skins.
